Hi all,
I am looking to initialize a branch run from a restart file (on CESM 2.1.3. with CAM6) on the B1850 compset. The restart file I intend to use is b.e21.BCO2x4cmip6.f09_g17.CMIP6-abrupt4xCO2.001 from the NCAR restart library.
my question is, in order to maintain continuity between my branch run and the restart file do I need to match the restart files XML / namelist variable changes?
e.g. this specific restart file has set the CAM namelist variables:
co2vmr=1138.8e-6
co2_cycle_rad_passive=.true.
do I need to match those in my branch run's XML? or will restart file apply those changes to my branch by default?
Additionally, how does one determine which XML variables need to match the restart file to ensure continuity and which do not? i.e. I can change the branch's fincl and nhtfrq and still maintain continuity, but if I do not change the co2vmr in the branch run to match the restart files I could potentially cause a discontinuity. So how do I make sure my branch's variables are configured such that I will not cause any discontinuities when branching from the restart?
Thanks very much!
